I updated from 1.41.3 to 1.42.3 today, with no errors reported by MediaWiki following the update. Viewing the wiki is working fine as far as I can tell, but I'm unable to load either the Visual Editor or the Wikitext Editor; if I go to my preferences page, I also can't switch tab (it loads "User profile", but clicking on any of the others has no effect).
When going into the browser console, I see this message:
The resource from “http://10.0.0.19/wiki/load.php?lang=en-gb&modules=startup&only=scripts&raw=1&safemode=1&skin=vector” was blocked due to MIME type (“text/html”) mismatch (X-Content-Type-Options: nosniff).
as well as a 500 response to the GET request for that URL.
It appears at least once on all pages; on the preferences page or on edit pages it appears twice. It appears regardless of what skin I have enabled (since preferences won't let me load the "Appearance" tab, I have to change by disabling Vector and switching the default skin in LocalSettings.php), and I have updated my skins to make sure they are the most recent available version.
When I go to that resource URL, I WAS also getting this error:
[8214b8572551d262133baaf6] /wiki/load.php?lang=en-gb&modules=startup&only=scripts&raw=1&safemode=1&skin=vector Error: Class "ResourceLoaderSkinModule" not found

#11 {main}From my understanding ResourceLoaderSkinModule was removed in an earlier version, so I have no idea what was trying to access it.
However, I'm now getting the same error but for a "ResourceLoaderOOUIIconPackModule" class instead. When I go looking for this, it seems to be a file that should be under "includes/ResourceLoader/", but this file simply doesn't exist on my system. I even re-downloaded the 1.42.3 files to double check and it's not there. As far as I can tell it too has been removed.
